ABSTRACT
Polarization dynamics in coherent arrays of vertical-cavity surface-emitting lasers are studied experimentally. The two degenerate polarization lasing modes expected in infinitely large arrays are observed at different frequencies in finite-size structures. The frequency splitting increases with decreasing array size and reaches 60 GHz in 2 × 2 arrays. This splitting is attributed to the coupling of the two polarization states through depolarization and scattering effects at the boundary of the array. Small arrays lase in the two-frequency regime, whereas large ones oscillate in the single-frequency domain.

    Vertical-cavity surface-emitting lasers (VCSELs) consist of a gain medium in which feedback is generally accomplished by two distributed Bragg reflectors (DBRs), for which sufficient reflectivity has to be achieved in order to obtain laser emission. As a consequence, DBRs generally consist of...

In a microcavity, the spontaneous emission rate can be greatly enhanced compared with that in free space. This so-called Purcell effect can dramatically increase laser modulation speeds,...
